## How do you solve 4x 2y 4?

- 4x-2y=4. 4x−2y=4. Subtract 4x from both sides. Subtract 4x from both sides.
- -2y=4-4x. −2y=4−4x. Divide both sides by -2. Divide both sides by −2.
- y=2x-2. y=2x−2.

## How do you do substitution?

The method of substitution involves three steps:

- Solve one equation for one of the variables.
- Substitute (plug-in) this expression into the other equation and solve.
- Resubstitute the value into the original equation to find the corresponding variable.

**What is the slope for 4x 2y?**

Reorder 5 5 and −2x – 2 x . Using the slope-intercept form, the slope is −2 .

### How do you find the slope of y 3x 4?

Explanation:

- Any linear equation in the form. y=mx+b. is said to be in slope-intercept form with slope m and y-intercept b.
- y=3x+4 is in this form. So the slope is 3 and the y-intercept is 4.
- To find the x-intercept, set y=0 and solve for x. 0=3x+4.

### How do you solve equivalent equations?

Rules for getting equivalent equation:

- Adding (subtracting) same number (or expression) to both sides of the equation will give equivalent equation.
- Multiplying (dividing) both sides of the equation by the same non-zero number (or expression) will give equivalent equation.

**How do you find equivalent equations?**

Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation….For example, these three equations are equivalent to each other:

- 3 + 2 = 5.
- 4 + 1 = 5.
- 5 + 0 = 5.

## How do you write an addition equation?

To write a proper addition equation, you have an equals sign. One side shows you the total. The other side shows you what things are being added together. You can have a variable on either side of the equation.
